There are a lot of potential fans out there considering how many people obsess over the British Royal family -- and over how many young (and old) women dream about marrying into one. This TV series will have special resonance since it's about a gawky commoner who does exactly that.
At least that commoner is played by the delightful Yun Eun Hye who brings the character to life in an uninhibited way. Even when she's over-acting, she seems entirely natural. But if you want to see her at her best, check out the much better romantic comedy/drama COFFEE PRINCE (aka, 1ST SHOP OF COFFEE PRINCE).
This one flows along nicely enuf. Unlike American series which are intended to go on forever, this had a definite time limit, so it had a definite arc. Still, maybe the plot would have worked better at less than 24 episodes. But you may find an actor or character you like and latch on happily for the duration.
Unlike American series, this is bright and colorful (almost gaudy at times). There are better Korean shows out there for grownups -- unless you're a grownup obsessed with royalty -- then this may be your ideal show.
